Amplite® Colorimetric Gama-Glutamyltransferase (GGT) Activity Assay Kit

Amplite® Colorimetric Gama-Glutamyltransferase (GGT) Activity Assay Kit is a colorimetric assay kit for measuring GGT activity in cells, tissue extracts, and serum using a substrate-based absorbance readout.

Colorimetric detection: GGT converts the assay substrate into a colored product.
Rapid workflow: Incubate for 10–30 minutes at 37 °C before reading.
Broad sample compatibility: Suitable for cells, tissue extracts, and serum samples.
Microplate compatible: Read absorbance at 418 nm using a clear-bottom plate.
Applications: Suitable for GGT activity measurements and research related to liver function and oxidative stress.

The pNA dose response was measured using the Amplite® Colorimetric Gama-Glutamyltransferase (GGT) Activity Assay Kit on a 96-well clear bottom microplate. The measurements were taken at 418 nm with a ClarioStar microplate reader (BMG).

Overview

The Amplite® Colorimetric Gamma-Glutamyltransferase (GGT) Activity Assay Kit provides an efficient and straightforward method for measuring GGT activity across various sample types. This assay utilizes a coupled enzyme reaction in which GGT catalyzes the conversion of a substrate into a colored product detectable at 418 nm, directly reflecting the GGT concentration in the sample. It is compatible with a wide range of biological samples, including cells, tissue extracts, and serum, and is suitable for high-throughput systems. γ-Glutamyltransferase (also known as GGT) is a mammalian enzyme playing an important role in the anti-oxidant defense mechanism of cells. It is located in cell membranes and is known for facilitating the transfer of γ-glutamyl moieties between molecules during glutathione regulation and xenobiotic detoxification. Elevated levels of serum GGT are linked to cardiovascular and liver diseases, metabolic syndrome, and oxidative stress. Consequently, GGT is a valuable biomarker for liver dysfunction and disorders related to oxidative stress.
